Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
